Altares investigates how humans construct sacred spaces, from the formal architecture of churches and cathedrals to the spontaneous memorials built by communities on roadsides to mark the place where someone died. Working with a large-format analog camera and a redscale technique, exposing the film through the base rather than the emulsion, each space is photographed in a single, slow exposure. The resulting images, printed as lightboxes, render these spaces in deep red tones, making visible a dimension of light and presence that the naked eye cannot perceive. The series began in Chile in 2021 and currently includes five works across churches, cathedrals, and animitas, two of which are held in private collections in Santiago.
